For non-flying fun with pilots, friends, and family.
Ski trips, Ethiopean-nights, movies, biking, climbing... All that fun stuff you can't do in the sky.

Oct 2014 Lunar Eclipse : Selenelion !!!

On Oct. 8, Interested skywatchers should attempt to see the total eclipse of the moon and the rising sun simultaneously. The little-used name for this effect is called a "selenelion," a phenomenon that celestial geometry says cannot happen.
Weather permitting, you could have a short window of roughly 2 to 9 minutes (depending on your location) with the possibility of simultaneously seeing the sun rising in the east while the eclipsed full moon is setting in the west.
The only reason that it can happen is that the refraction from Earth's atmosphere makes it appear that the Moon is still up (after it has actually set), and that the Sun is already up (before it has actually risen).

Now that is pretty darn cool! Planning to hit a local parking garage that has good east & west views, shortly before sunrise..... Sorry not to have posted about this sooner! :(

So I never followed up on this topic.... Got up at the crack-o-dawn, headed to a location with great views to the E and W, and was pleased to see a tawny, fully-eclipsed moon lowering in the west....

Until it sank into fog/cloud/haze, disappearing from sight before sunrise.

Sigh.

But the next Selenelion...? I'm there!!!!! :-)
